What you are getting

A Kool Stop BMX threaded brake shoe in black, KS-BMXB, made in the United States. Package 17.78 × 10.41 × 1.78 cm (7 × 4.1 × 0.7 in), 0.050 lb — about 23 g (0.8 oz). $12.17.

“Threaded” in the title is the whole fitment fact

Brake shoes attach in two ways, and they are not interchangeable:

  • a smooth post slides into a slot on the brake arm and is clamped by a bolt, with curved shims setting the angle — that is the CNC and Chooee blocks on this page, which ship with nuts and shims
  • a threaded post passes through a hole in the arm and takes a nut on the far side, with no angular adjustment

This is the threaded kind, and it is the only one in the group. BMX and older calliper brakes use it; a modern V-brake arm does not have the hole.

If the shoe coming off your bike has a nut on the back of the arm, this is the family. If it is clamped in a slot, it is not.

And the listing contains nothing else

Four bullets: package dimensions, “Product Type: Vehicle Brake Pad”, package weight, and “Country Of Origin: United States”. The description field is the words “Product Description” and nothing after them.

No length. No width. No compound. No rim material. No quantity — whether KS-BMXB is one shoe or a pair is not stated, and the package weight of 0.050 lb suggests one.

That is the thinnest listing in the American survey for this shelf, and it is a brand with a reputation for compound.

Kool Stop makes compound its business, and this page does not mention it

Kool Stop is known for naming and color-coding its pad compounds — the practice of selling the same shape in a salmon-colored all-weather compound, a black compound and a dual compound is theirs. None of that is on this listing.

So the one thing a buyer would come to Kool Stop for is absent, and the only clue is the B in KS-BMXB, which conventionally means black.

Shop by the model code and check the compound with the seller.

Made in the USA, stated

The only item on this page with a country of origin. On a part whose compound is the product, where it is made is a reasonable proxy for consistency, and it is the one positive fact the listing offers.

What is not published

No length, no width, no quantity, no compound, no rim material, no weight for the shoe itself — only the package. Four bullets, three of which describe the box.

At $12.17 it is dearer than every V-brake block here and buys a single threaded shoe of unstated size, from a brand whose compounds are the reason to choose it.

The questions riders ask

How do I know my brake takes a threaded shoe?

Look behind the brake arm. A threaded post passes through a hole and takes a nut on the far side — no slot, no shims, no angular adjustment. A smooth post slides into a slot and is clamped by a bolt, with curved shims setting the toe-in; that is what the CNC and Chooee blocks on this page are, and why they ship with nuts and shims. The two do not substitute.

Which compound is it?

The listing does not say, which is the odd part — compound is what Kool Stop is known for, and the practice of selling one shape in several named compounds is theirs. The only clue is the B in KS-BMXB, which conventionally means black. If the choice between an all-weather compound and a dry one matters to you, ask the seller before ordering.

Is it one shoe or a pair?

Not stated. The package weight of 0.050 lb, about 23 g (0.8 oz), points to a single shoe — for comparison, the Shimano BR-CT91 on this page is 30 g (1.1 oz) per piece. A brake needs two, and a bike needs four. Confirm the quantity before ordering, because at $12.17 a single shoe this is the most expensive rim stopper on the page by a considerable margin.
